noun that l, FREDERICK MITCHELL, rs, in county of llestchester and of New "1' ork, have invented a new and uscflfl Improvement in Signs, of which the? "ollowing is u full,'clcar, and exact descripr1051.

My invention relates to an improvement in in curves, ssh

To that end he invention consists in lhe" had to the accompanying art of this specification, of reference indicate all. she views.

3 is u perspective view of one of the letters detached from the siguplute,

The prime object of the invention is to provide 2. heckgronud. to constitute the body of the sign, upon which any Word may be rupidly constructed,'oud the letters throughout 3 may be changed into other words, as may be desired. I

To "that end the body of the design consists of u perforated plate, which plate is preferably mounted in a suitable framell. The 5,0 plate is ordinarily constructed of metal, but

' he of any other desired material. It is e in the some manner as the Well-known uted plate of commerce. The perforu.- l in the plate may be arranged in any {1 manner one "may L made cover the 137 a portion of the saw :Eoruiious cru yed are ordinarily cird is 1; out lhcyma-yhe d, u? own in 3, or may v desired contour.

1 practice refer The letters 13 may be constructed of any suitable 1ncteriul-such as metal, wood, glass, ivory, rubber, (ides-311d may be of any form, with plain or with ornamental surfaces. When the circular form of perforation is employed, each letter is provided with one or more (preferably two) studs 14, which studs are projected from the rear face of the letter, and may be either attached thereto or formed integrally therewith. The upperfstnld is curved upwardflhns forming a hook, so that in applying a letter 13 to the plate 10 the said letter must be held at on acute ahgle to the latter, in order to permit insertion. of such hook, and then lowered or brought down to the vertical position, (shown in full liucs,) when the free end of the hook Will enter the perforation above that in which its body rests. The lciter is thus hold suspended by the hook 5 but it ad viseble to u psct the end of the lower stud, in order to hold the lower end of the letter firmly egciust i'he plate 10. it will be understood that the letters, as aforesaid, may be placed diagonally of the perforated plate, or in. on rvcd lines, or horizontally, as the fancy of the operator may dictate. The upper stud is bent upou itself to assume u curved or e diagonal line, preferably the former and when the letter 1s to be placed in position on the body-plate the hook ehus formed, which is also illustrated in. Fig. 2, is first. introduced into the perforation, the letter being held at an angle to the plate, and then the letter is brought to a perpendicular position parallel to and in. Contact. with the plate, whereupon the lower stud will, as the letter swings downward, enter one of the perforations.

Any number of studs may be employed in connection with the letters, and the said studs may be distributed in a manner to best sushaving a series of perforations one above another, of a letter having a fixed curved stud having a fixed curved prong on its back, as or prong on its back, which is adapted to pass and for the purpose specified. freely through said perforations, as S1105Vn FREDERICK MITCHELL, and described, whereby said letter may be- Witnesses: attached and held suspended against the face M.
